Invitae | RCV002239102 | SCV002509506 | uncertain significance | Ataxia-telangiectasia-like disorder | 2022-08-19 | criteria provided, single submitter | clinical testing | This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 618 of the MRE11 protein (p.Met618Thr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MRE11-related conditions. ClinVar contains an entry for this variant (Variation ID: 1681560). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
Ambry Genetics | RCV002463146 | SCV002754821 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-05-26 | criteria provided, single submitter | clinical testing | The p.M618T variant (also known as c.1853T>C), located in coding exon 15 of the MRE11A gene, results from a T to C substitution at nucleotide position 1853. The methionine at codon 618 is replaced by threonine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
